[Dr Graeme Codrington] “I’m an alien. I’m a legal alien. I’m an Englishman in New York”. The lyrics of Sting’s popular rendition fill my thoughts as I contemplate the similarities and differences between my life and the song. In my case I am not in New York nor am I am Englishman either. But I am effectively an alien living in another world: I’m a South African in London.
